What is Heat?
The exchange of energy due to difference in temperature is
called heat. But as a noun we can say that the Heat is the quality of being hot
or high temperature and to understand easily we can say that feeling of hot or
warm is heat.
What is Heat in Science ?
The exchange of energy due to difference in temperature is
called heat. We may also explain as, heat is the form of the energy that is
moved between two substances at different temperatures. Means if two substances
are in contact and one has 200K temperature and other have 100K temperature
then the direction of energy flow is from the substance at the higher
temperature to the substance of lower temperature. Means in above case heat
flows from substance having 200k temperature to substance having 100K
temperature.
Heat is a form of energy so heat is measured in units of
energy, commonly calories or joules.
What is Temperature?
Temperature is the quantity of hotness or coldness of any substance. Simply we can say that Temperature is the measurement of how much an object is hot or cold.
What is Temperature in Science ?
Temperature is the quantity of hotness or coldness. Also in
scientific way, temperature is explained as the average kinetic energy per
molecule of a substance. Heat and Temperature (Temp, T) are two different terms
and have different meanings so don’t get confuse between them. Heat is energy while temperature is not
energy. Heat is measured in Joules while temperature is measured in Celsius
(C), Fahrenheit (F) or Kelvin (K). Symbol used for heat is Q while symbol used
for temperature is T. SI unit of heat is Joule while SI unit of temperature is
Kelvin.
Heat VS Temperature in Chemistry
Heat is the flow of energy from hot object to cold object
while temperature is the measurement of how much an object is hot or cold. Heat
is energy while temperature is not energy. Heat is measured in Joules while
temperature is measured in Celsius (C), Fahrenheit (F) or Kelvin (K). Symbol
used for heat is Q while symbol used for temperature is T. SI unit of heat is
Joule while SI unit of temperature is Kelvin.
How to measure Temperature with Thermometer in degree Celsius & Fahrenheit
This video explains-
How do you measure temperature with a thermometer?
and How do you read a Fahrenheit and Celsius thermometer?
After watching this video on temp., you can easily check temperature with thermometer.
Temperature is the measure of hotness or coldness of an object.
To convert temperatures from Fahrenheit to Celsius,
use the formula C=(5/9)(F−32)
and for Celsius to Fahrenheit, use the formula F=(9C/5)+32.
How to convert Temperature from one Unit to Another
By using below temperature conversion calculator, you can convert temperature from degree celsius to degree fahrenheit, degree celsius to kelvin. Similarly, from degree fahrenheit to degree celsius & degree fehrenheit to kelvin. Similarly, from kelvin to degree celsius and kelvin to degree fahrenheit.
Relationship between degree Celsius and degree Fahrenheit
Use the formula ºC=(5/9)(ºF−32)
Relationship between degree Celsius and degree Kelvin
Use the formula K = ºC + 273.15
Relationship between kelvin and degree Fahrenheit
Use the formula K = 5/9 ºF + 459.67Thanks, Enjoy Learning Chemistry with "Chemistry Notes Info"!
